SAVE vs. IBR vs. PAYE: Which Income-Driven Plan Cuts Your Student Loan Bill the Most?
SAVE, IBR, and PAYE all cap payments by income — but SAVE saves most borrowers $125+/month vs. IBR. Here's the exact plan-by-plan math to choose correctly.

On the same $45,000 balance, SAVE produces a monthly payment of roughly $103. IBR produces $228. That $125 gap is real cash — $1,500 a year — and most borrowers don’t know they’re leaving it on the table.

SAVE, IBR, and PAYE — What Each Plan Actually Does
All three are income-driven repayment (IDR) plans. Each caps your monthly payment as a percentage of your discretionary income, then forgives whatever’s left after 20 or 25 years.
The differences are the caps, the forgiveness timeline, and who qualifies.
SAVE (Saving on a Valuable Education)
SAVE replaced REPAYE in 2023. It’s the most generous plan for most current borrowers.
- Payments capped at 5% of discretionary income for undergraduate loans (10% for grad-only; a weighted blend for mixed debt)
- Discretionary income defined as earnings above 225% of the federal poverty line — a higher threshold than older plans use
- No negative amortization: if your payment doesn’t cover accruing interest, the government waives the difference
- Forgiveness after 20 years (undergrad) or 25 years (grad)
- Borrowers with original balances of $12,000 or less get forgiveness after just 10 years
As of mid-2025, SAVE is under active litigation. Payments are paused for SAVE enrollees pending court rulings. Check StudentAid.gov for current status before enrolling.
IBR (Income-Based Repayment)
IBR has two versions, depending on when you first borrowed.
- New IBR (first loan disbursed July 1, 2014 or later): payments capped at 10% of discretionary income, forgiveness after 20 years
- Old IBR (borrowed before July 1, 2014): payments capped at 15% of discretionary income, forgiveness after 25 years
- Discretionary income = earnings above 150% of the federal poverty line — a lower exemption than SAVE
- Eligibility requires partial financial hardship: your IBR payment must be lower than what you’d pay on a standard 10-year plan
IBR’s advantage: it works on FFEL loans that other plans won’t touch, and its rules are legally settled.
PAYE (Pay As You Earn)
PAYE closed to new borrowers in July 2024. If you’re not already enrolled, this option is off the table.
- Payments capped at 10% of discretionary income — same as New IBR
- Forgiveness after 20 years — five years shorter than Old IBR
- Requires partial financial hardship and a specific borrowing window: no federal loan balance before October 1, 2007, plus a disbursement on or after October 1, 2011
The Side-by-Side Numbers
Scenario: $45,000 in federal undergraduate Direct Loans, 6.8% interest, single filer, $52,000 gross income, no dependents.

Total Cost Over the Life of the Loan
Monthly payment isn’t the full picture. Lower payments mean more interest accrues and a larger balance gets forgiven — which has tax implications. For more on this topic, see our guide: $25,000 Car Loan: Monthly Payment at Every Interest Rate in 2026.
The American Rescue Plan made forgiveness tax-free through 2025. Congress has not extended that treatment for 2026 and beyond. A $52,000 forgiven balance taxed at 22% federal = roughly $11,440 due in that calendar year. Plan a tax reserve now.
📊 Estimated 20-Year Total Cost — $45,000 Loan at 6.8%
Plan Total paid Est. forgiven balance Total interest accrued SAVE ~$24,700 ~$52,000 ~$31,700 New IBR ~$54,700 ~$27,000 ~$36,700 PAYE ~$54,700 ~$27,000 ~$36,700 Old IBR (25 yr) ~$102,600 ~$0 ~$57,600 Standard 10-year ~$62,200 $0 ~$17,200 Assumes 3% annual income growth, no refinancing, no PSLF. Forgiven balances may be taxable after 2025 — verify with a tax advisor. Income growth benchmark: Bureau of Labor Statistics.
SAVE delivers the lowest out-of-pocket total in this scenario. But it forgives the largest balance. If that forgiveness becomes taxable, you need a plan for the bill in year 20.
Who Should Pick Which Plan
Pick SAVE if: You have Direct Loans, primarily undergraduate debt, and a moderate income. The 5% cap and higher income exemption produce the lowest monthly payment of any plan. Confirm the litigation status at StudentAid.gov before enrolling.
Pick New IBR if: You want a legally settled plan while SAVE’s court battle plays out. New IBR also covers FFEL loans that SAVE won’t. The 10% cap costs more per month, but the rules aren’t going anywhere.
Pick PAYE if: You’re already enrolled. Stay if your payments are lower than IBR. You can’t join now, but existing enrollees keep access.
Use Old IBR only if: You borrowed before July 2014 and don’t qualify for newer plans. Or if you’re targeting PSLF — in that case, 10% on New IBR works the same way.
Targeting Public Service Loan Forgiveness? PSLF forgives after 120 qualifying payments — 10 years — with no tax hit. On that track, you want the lowest possible payment. SAVE or New IBR both qualify; pick whichever produces the smaller number.
Most borrowers earning between $40,000 and $70,000 with undergraduate debt will come out ahead on SAVE, assuming the plan survives litigation. The income exemption alone knocks hundreds of dollars off compared to IBR.
Three Moves That Lower Your Total Loan Cost
1. Recertify income annually — or early after a pay cut. IDR payments are based on your most recently certified income. If your income drops, recertify immediately — don’t wait for the annual deadline. A $10,000 income drop on SAVE cuts your payment by roughly $41/month, or $492/year.
2. File taxes separately if married. Joint income inflates your IDR payment. On SAVE, filing separately can cut your certified income — though you forfeit some tax benefits. Run both scenarios before deciding. Married borrowers with very different income levels often come out ahead filing separately by $1,000 to $2,000 on their annual tax bill, even after losing the marriage penalty adjustment.
3. Track your forgiveness clock carefully. Each year in repayment counts toward forgiveness — but only months with a qualifying payment or a qualifying deferment. Administrative forbearances like the current SAVE pause may or may not count, depending on how litigation resolves. Log every payment month. If your servicer has errors in your payment count, dispute them now, not in year 19.
Quick Answers About SAVE, IBR, and PAYE
What’s the main difference between SAVE and IBR? SAVE uses a higher income exemption (225% vs. 150% of the poverty line) and caps undergraduate payments at 5%, not 10%. On a $52,000 income, that’s $125 less per month — $1,500 a year.
Can I switch between plans mid-repayment? Yes, with no penalty. Switching may reset some forgiveness timeline calculations depending on the plans involved. Confirm with your servicer before switching — get it in writing.
Does SAVE still exist in 2025? SAVE is in legal limbo. A federal court challenge paused implementation. Enrollees are in administrative forbearance, and interest is not accruing during the pause. Whether paused months count toward forgiveness is unresolved. Check StudentAid.gov for the latest.
Is IBR better than refinancing to a private loan? Usually no, if forgiveness or PSLF is in play. Refinancing to a private lender eliminates all IDR options permanently. If you earn well above average and can pay off the balance in five to seven years, a lower private rate saves money on interest. Any chance you’ll need income-based payments or forgiveness? Stay federal.
What happens to taxes on forgiven balances? Forgiveness is tax-free through 2025 under current law. After that, forgiven balances revert to taxable income unless Congress acts. Several states already tax forgiven balances regardless of federal treatment. Check your state’s rules and set aside a tax reserve if your forgiveness date is after 2025.
